All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

The charging state control method, the charging state control device, the electronic equipment and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

The charging state control method can be applied to the terminal, and can be specifically executed by hardware or software in the terminal.

The terminal includes, but is not limited to, a portable communication device such as a mobile phone or tablet computer. It should also be appreciated that in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer.

The implementation main body of the charge state control method provided in the embodiment of the present application may be an electronic device or a functional module or a functional entity capable of implementing the charge state control method in the electronic device, where the electronic device mentioned in the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a camera, a wearable device, and the like, and the charge state control method provided in the embodiment of the present application is described below by taking the electronic device as an implementation main body as an example.

As shown in fig. 1, the charge state control method includes: step 110 and step 120.

Step 110, acquiring a real-time electric signal of a powered device;

in this step, the real-time electrical signal may include: real-time charging current, real-time charging power, real-time charging voltage, etc., the present application is not limited herein.

The real-time electric signal is an electric signal extracted from the power supply equipment and can be reflected on the power supply signal of the power supply equipment.

It can be understood that the same technical effect can be achieved by replacing the current criterion with the power criterion or assisting in voltage judgment. Likewise, the same technical effect can be achieved by changing the power criterion to the current criterion.

In the actual execution process, the real-time electric signals corresponding to the powered equipment at the current acquisition time can be acquired at each acquisition time, the acquired real-time electric signals are stored in a local or cloud database, and the acquired real-time electric signals are acquired when required.

For example, with the time period T as a window, the real-time electrical signal during the time period is collected and recorded, wherein T > 0.

And step 120, determining that the powered device enters a suspended charging state and controlling the access module to enter a normally open state when the real-time electric signal is smaller than the first electric threshold, the duration of the real-time electric signal smaller than the first electric threshold exceeds the first time threshold, and the real-time electric signal meets the jump starting detection condition.

In this step, the first electrical threshold and the first time threshold are both preset values.

The values of the first electrical threshold and the first time threshold may be user-defined based.

Wherein the type of electrical signal of the first electrical threshold should be consistent with the type of real-time electrical signal.

The following describes a determination manner that the real-time electrical signal satisfies the jump start detection condition from two different implementation angles.

1. Determination based on front-to-back electrical signal change condition

In some embodiments, the determination that the real-time electrical signal satisfies the transition start detection condition may be as follows: and under the condition that the change degree of the real-time electric signal is larger than the target range, determining that the real-time electric signal meets the jump starting detection condition.

In this embodiment, the target range is a preset value.

The value of the target range may be user-defined based.

The type of electrical signal corresponding to the target range should be consistent with the type of real-time electrical signal.

The degree of change is used to represent the maximum change value of the real-time electrical signal within the target period, and the maximum change value is used to represent the change condition of the real-time electrical signal within the target period.

The target time period is a time period formed by reversely pushing forward for a certain time length by taking the current acquisition time as an endpoint after the power receiving equipment is connected to the charging equipment.

In some embodiments, the degree of variation may be determined by:

and determining the degree of change based on the difference between the real-time electrical signal corresponding to the first target time and the real-time electrical signal corresponding to the second target time.

In this embodiment, the first target time and the second target time are respectively acquisition times within the target period.

In the case where the second target time is the current acquisition time, the first target time may be any acquisition time preceding the current acquisition time in the target period.

Or, in the case that the second target time is the current acquisition time, the first target time may be the acquisition time corresponding to the largest real-time electrical signal in the target period.

Or, in the case that the second target time is the acquisition time corresponding to the smallest real-time electric signal in the target period, the first target time may be the acquisition time corresponding to the largest real-time electric signal in the target period.

The manner of determining the degree of change will be specifically described below from the above three cases, respectively.

The change degree can be the change degree between the real-time electric signal corresponding to the current acquisition time and the real-time electric signal corresponding to the first target time, and the first target time is any acquisition time before the current acquisition time in the target period.

In this embodiment, the target time is any one of the acquisition times within the target period.

For example, the change degree of the real-time electric signal may be represented by a difference value between the real-time electric signal corresponding to the current acquisition time and the real-time electric signal corresponding to the previous arbitrary acquisition time, such as the change degree father=pi-Pcur; pi is a real-time electric signal corresponding to the first target moment; and Pcur is a real-time electric signal corresponding to the current acquisition time.

Secondly, the change degree of the real-time electric signal can be represented by the difference value between the real-time electric signal corresponding to the current acquisition time and the largest real-time electric signal in the target period, and if the change degree=pmax-Pcur; wherein Pmax is the maximum real-time electrical signal in the target period; pcur is the real-time electrical signal.

Thirdly, the change degree of the real-time electric signal can be expressed by the difference value between the largest real-time electric signal and the smallest real-time electric signal in the target period, such as father=pmax-Pmin; wherein Pmax is the maximum real-time electrical signal in the target period; pmin is the smallest real-time electrical signal within the target period.

Of course, in other embodiments, other ways of obtaining the degree of change of the real-time electrical signal may be used, which is not limited herein.

The implementation of step 120 is described below using the real-time electrical signal as an example of real-time charging power.

When the powered device is detected to be connected or starts to charge, the real-time charging power Pcur during the period is collected and recorded by taking the duration T as a window (namely a target period).

And if the real-time charging power Pcur at a certain collecting moment is more than or equal to the first electric threshold P1, returning to the real-time charging power collecting step.

If the real-time charging power Pcur at a certain acquisition time is less than the first electrical threshold P1, it is further determined whether the degree of change of the real-time electrical signal is greater than the target range, for example, by the formula:

Pi–Pcur>P2

pi is a real-time electric signal corresponding to a target moment, namely a real-time electric signal corresponding to a real-time charging power target moment at any acquisition moment acquired during a window with the current acquisition moment backward pushing time length of T; p2 is the target range.

If Pi-Pcur > P2 is not satisfied, returning to the real-time charging power acquisition step.

If Pi-Pcur > P2 is satisfied, it is further determined whether the real-time charging power Pcur is smaller than the first electrical threshold P1 and the duration exceeds the first time threshold t1.

If the power consumption is smaller than the first electric threshold P1 and the maintaining time length exceeds the first time threshold t1, determining that the power receiving equipment has power jump currently, determining that the power receiving equipment is in a suspension charging state, and controlling the access module to be normally open.

If the duration less than the first electrical threshold P1 is not satisfied and exceeds the first time threshold t1, returning to the real-time charging power acquisition step.

Of course, in other embodiments, the three determining steps of the real-time electrical signal being smaller than the first electrical threshold, the duration of the real-time electrical signal being smaller than the first electrical threshold exceeding the first time threshold, and the degree of change of the real-time electrical signal being greater than the target range may be performed simultaneously or may be performed sequentially in any order, which is not limited herein.

It should be noted that, only if the above three determination conditions are satisfied, it is determined that the power receiving apparatus is in the suspended charging state, and the control path module is normally open.

2. Time-based determination

In some embodiments, the determination that the real-time electrical signal satisfies the transition start detection condition may be as follows:

and under the condition that the continuous times of the real-time electric signal larger than the sixth electric threshold value is larger than the threshold value, determining that the real-time electric signal meets the jump starting detection condition.

In this embodiment, the sixth electrical threshold and the threshold are both preset values.

The values of the sixth electrical threshold and the threshold may be user-defined based.

The implementation of this embodiment will be described below taking a real-time electric signal as an example of real-time charging power.

As shown in fig. 5, the device acquires the real-time electrical signal of charging after starting charging, and the power jump detection function is in a closed state.

When the real-time charging power > sixth electrical threshold P3 is satisfied, the internal Counter starts counting;

when the real-time charging power > sixth electrical threshold P3 is not satisfied, the internal Counter value is cleared.

When the count of the Counter is larger than the threshold value N1, the jump starting detection condition is determined to be met, and the power jump detection function is started.

After the power jump detection function is started, whether the real-time charging power is smaller than a first electric threshold value or not is judged, and the duration of the real-time charging power smaller than the first electric threshold value exceeds a first time threshold value.

If the real-time charging power is continuously smaller than the first electrical threshold P1 and the maintaining time length exceeds the first time threshold t1, the power jump is considered to occur, and the powered device is determined to be in a state of suspending charging.

With continued reference to fig. 5, in some embodiments, the power jump detection function is turned off when the real-time charging power is continuously less than the seventh electrical threshold P7 and the duration of the hold exceeds the eighth time threshold t 8.

Wherein the first time threshold t1 is less than the eighth time threshold t8, and the sixth electrical threshold P3 is greater than or equal to the seventh electrical threshold P7> the first electrical threshold P1.

According to the charge state control method provided by the embodiment of the application, whether the jump starting detection condition is met is judged through the continuous times that the real-time electric signal is larger than the sixth electric threshold, a large amount of data is not required to be recorded, the data storage space is saved, and the calculation efficiency is improved.

The inventor finds that in the research and development process, in the related technology, the output current/output voltage/output power is mainly detected, and if the output current/output voltage/output power is smaller than a certain threshold and lasts for a certain time, the equipment is considered to be full or no electricity is required, so that the output channel is closed. However, this technique has the following problems:

1) When the charging power is high, the ambient temperature is high or the heat dissipation effect is poor, the power receiving equipment is over-high, the power receiving equipment can be triggered to stop receiving energy, and the energy supplied by the power supply equipment can be continuously received until the temperature of the power receiving equipment is reduced; during over-temperature, the output current/output power is almost zero.

2) Part of current powered devices are provided with an intelligent charging mode, namely, when a charging source is accessed for a long time, the intelligent power receiving device intelligently distributes the time for receiving energy until the power receiving device is full by learning the charging habit of a user; for this mode, the output current/output power is almost zero during the period when the power receiving apparatus stops accepting energy.

3) Currently, intermittent electric equipment exists, and the energy supply required by the work of the intermittent electric equipment is also intermittent; the output current/output power is also almost zero when the powered device is in a suspended operation.

For the above cases, if the above method is still used to determine whether the powered device is full or not in a dead electricity demand, the output current/output power is almost zero when the powered device is in a state of suspending charging or intermittent power consumption, and at this time, the powered device is erroneously identified as the full/dead electricity demand of the device, so that the output path is closed, and the powered device cannot be fully filled or cannot be restarted finally, which affects the charging effect and also affects the user experience of the user.

In the application, whether the jump starting detection condition is met is judged by comparing the change degree of the real-time electric signal with the second threshold value or by comparing the continuous times that the real-time electric signal is larger than the sixth electric threshold value, and the jump detection is started under the condition that the jump starting detection condition is confirmed to be met, so that whether the jump occurs is further detected.

When detecting whether jump occurs, whether jump occurs is judged based on the duration that the real-time electric signal is smaller than the first electric threshold value, so that the electric signal reduction condition caused by jump or full power (in the constant voltage charging stage, the charging current shows a slow reduction trend along with the rising of the electric quantity of the powered equipment) can be effectively distinguished, and the purpose that whether the powered equipment enters the full state or enters the suspension charging state is achieved by detecting whether the jump exists in the electric signal is achieved.

Under the condition that the jump starting detection condition is met and the jump occurs, the power receiving equipment is controlled to enter a suspension charging state, the influence of acquisition errors existing in the acquisition process on the result can be eliminated, and the detection is sensitive and high in detection precision.

According to the charging state control method provided by the embodiment of the application, the real-time electric signal of the power receiving equipment is judged by integrating whether the power receiving equipment meets the jump starting condition, whether the jump occurs or not and other conditions, and the pause charging state and the full-charge state of the power receiving equipment can be effectively distinguished, so that the accuracy and the precision of a judging result are improved, the method is suitable for intermittent electric equipment, and has a wide use scene.

As shown in fig. 2, in some embodiments, after determining that the powered device enters a suspended state of charge, the method may further include:

determining that the powered device exits the suspended state of charge if the real-time electrical signal is greater than the second electrical threshold and the duration is not less than the second time threshold;

a real-time electrical signal of the powered device is acquired.

In this embodiment, the second electrical threshold and the second time threshold are preset values.

The values of the second electrical threshold and the second time threshold may be user-defined based.

Wherein the type of electrical signal of the second electrical threshold should be consistent with the type of real-time electrical signal.

The implementation of this embodiment will be described below taking a real-time electric signal as an example of a real-time charging current.

Under the condition that the powered device is in a suspended charging state, if the real-time charging current is greater than a second electrical threshold I1 and the duration time is greater than or equal to a second time threshold T2, determining that the powered device exits the suspended charging state, and returning to a window data acquisition state taking T as the duration time.

According to the charging state control method provided by the embodiment of the application, after the powered device is determined to be in the suspended charging state, the change of the state of the powered device can be timely detected by continuously monitoring the change of the real-time charging current and the like of the powered device, so that corresponding steps are executed, and the method has higher response timeliness and higher sensitivity.

With continued reference to fig. 2, in some embodiments, after acquiring the real-time electrical signal of the powered device, the method may further include:

when the real-time electric signal is smaller than the third electric threshold and the duration is not smaller than the third time threshold, and the real-time electric signal does not meet the target condition, determining that the power receiving equipment is in a full-power state, and controlling the access module to enter a closed state;

In this embodiment, the third electrical threshold and the third time threshold are preset values.

The values of the third electrical threshold and the third time threshold may be user-defined based.

Wherein the type of electrical signal of the third electrical threshold should be consistent with the type of real-time electrical signal.

The implementation of this embodiment will be described below by taking a real-time electric signal as an example of a real-time charging current.

As shown in fig. 2, when the real-time charging current is less than the third electrical threshold I2 for a period of time longer than or equal to the third time threshold t3 while in the state group 1, the powered device is considered to be fully charged, and the power-on module is controlled to be turned off.

It should be noted that, in this embodiment, the priority of the full power detection path should be lower than that of the power jump detection path.

That is, the full power detection flow is executed only if at least one of three conditions, that is, a duration in which the real-time electric signal of the power receiving apparatus is smaller than the first electric threshold value, a duration in which the real-time electric signal is smaller than the first electric threshold value, exceeds the first time threshold value, and a degree of change in the real-time electric signal is greater than the second threshold value, is not satisfied.

For example, when the target condition is satisfied simultaneously with "the real-time electric signal is smaller than the third electric threshold value and the duration is not smaller than the third time threshold value", the power receiving apparatus should be preferentially controlled to enter the suspended state of charge.

According to the charging state control method provided by the embodiment of the application, whether the power receiving equipment enters the full-power state is further judged based on the size of the real-time electric signal, the duration and other conditions under the condition that the power receiving equipment is prevented from entering the suspended charging state, and the closing access module is timely controlled under the condition that the power receiving equipment is determined to enter the full-power state, so that the power consumption of the power supply equipment can be effectively saved, and the battery life of the power receiving equipment is prolonged.

With continued reference to fig. 2, in some embodiments, after determining that the powered device enters a suspended state of charge, the method may further include:

In this embodiment, the fourth electrical threshold and the fourth time threshold are preset values.

The values of the fourth electrical threshold and the fourth time threshold may be user-defined based.

Wherein the type of electrical signal of the fourth electrical threshold should be consistent with the type of real-time electrical signal.

For example, when the powered device is in a state of suspending charging, if the real-time charging current is smaller than the fourth electrical threshold I3 and the duration is longer than or equal to the fourth time threshold t6, the charging interface connected to the powered device is controlled to enter the sleep state.

According to the charging state control method provided by the embodiment of the application, the charging interface is controlled to enter the dormant state when the powered device is determined to be in the state of suspending charging, so that the power consumption of the power supply device can be further saved.

With continued reference to fig. 2, in some embodiments, after controlling the charging interface of the charging device connected to the powered device to enter the sleep state, the method may further include:

Under the condition that different charging interfaces do not share the same power supply, the charging power corresponding to the charging interface entering the dormant state is released to other charging interfaces.

In this embodiment, it can be appreciated that in the case where different interfaces share the same power supply (including, but not limited to, direct current-direct current (DC-DC), alternating current-direct current (AC-DC) and low dropout linear regulators (low dropout regulator, LDOs), and power is not directly delivered to the output interface via other power modules, when multiple interfaces are simultaneously operated, there may be a difference in voltage levels of the fast charge protocol requested by the different interfaces, which cannot be simultaneously operated in the fast charge state.

Under the condition that different interfaces share the same power supply, when the powered device is identified to be in a state of full charge, no power consumption requirement or unplugging and the like, the power supply path of the current charging interface can be closed, so that the other charging interfaces can work in a fast charging state to optimize power distribution.

In an application where different interfaces do not share the same power supply, the different power supplies may be at different voltage levels, and when it is identified that the powered device is in a full, no power consumption requirement, or unplugged state, the power supply path of the current charging interface may be selectively turned off, and power may be released to the remaining online charging interfaces, or power may be directly released to the remaining online interfaces, so as to optimize power distribution.

The implementation of this embodiment will be described by taking a real-time electric signal as an example of a real-time charging current.

For example, when the powered device is in a state of suspending charging, if the real-time charging current is smaller than the fourth electrical threshold I3 and the duration is longer than or equal to the fourth time threshold t6, controlling the charging interface connected to the powered device to enter a sleep state; and then judging whether the charging interface and other charging interfaces share the same power supply.

Under the condition that the same power supply is not shared, the charging power occupied before the charging interface can be released to other charging interfaces so as to optimize power distribution and improve the overall charging efficiency.

According to the charging state control method provided by the embodiment of the application, under the condition that different charging interfaces do not share the same power supply, the power distribution can be optimized by releasing the charging power corresponding to the charging interface entering the dormant state to other charging interfaces, so that the overall charging efficiency is improved.

And controlling the charging interface to exit from the sleep state under the condition that the real-time electric signal is larger than the fifth electric threshold and the duration is not smaller than the fifth time threshold.

In this embodiment, the fifth electrical threshold and the fifth time threshold are preset values.

The values of the fifth electrical threshold and the fifth time threshold may be user-defined based.

Wherein the electrical signal type of the fifth electrical threshold should be consistent with the type of the real-time electrical signal.

For example, when the charging interface is in the sleep state, if the real-time charging current corresponding to the charging interface (i.e., the real-time charging current of the powered device connected to the charging interface) is suddenly greater than the fifth electrical threshold I4 and the duration exceeds the fifth time threshold t7, the charging interface is controlled to exit the sleep state, and the access module is kept in the normal-on state.

According to the charging state control method provided by the embodiment of the application, after the charging interface enters the dormant state, the real-time electric signal is continuously monitored to timely adjust the corresponding control strategy based on the change of the electric signal, so that the charging state control method has higher response timeliness and higher sensitivity.

With continued reference to fig. 2, in some embodiments, after controlling the powered device to enter a suspended state of charge, the method may further include:

and in the case that the duration of the suspension state of charge is not less than the sixth time threshold, or in the case that the duration of the charging interface of the charging device connected with the powered device enters the sleep state is not less than the seventh time threshold, the control path module enters the closed state.

In this embodiment, the sixth time threshold and the seventh time threshold are preset values.

The values of the sixth time threshold and the seventh time threshold may be user-defined based.

For example, when the duration of the power receiving device continuously being in the suspended state of charge is greater than or equal to the sixth time threshold t4, or the duration of the charging interface continuously being in the dormant state is greater than or equal to the seventh time threshold t5, the power receiving device is considered to be full, the path module is forcibly turned off, and the algorithm is reset, and the power receiving device is waited for to be accessed again or waited for to start charging again.

It should be noted that, the priority of the timeout determination flow provided in this embodiment is lower than that of the determination mechanism for recovering the sampling state of the powered device with the duration T as the window, but higher than that of the sleep mechanism flow.

For example, in the case where "the real-time charging current is greater than the second electrical threshold I1 and the duration is greater than or equal to the second time threshold t2" and "the suspension charging state duration > the sixth time threshold t4 or the duration in the sleep state > the seventh time threshold t5" occur simultaneously, a path in which "the real-time charging current is greater than the second electrical threshold I1 and the duration is greater than or equal to the second time threshold t2" is preferentially executed;

for another example, when the "real-time charging current is smaller than the fourth electrical threshold I3 and the duration is longer than or equal to the fourth time threshold t6" and the "suspension charging state duration > sixth time threshold t4 or the duration in the sleep state > seventh time threshold t5" occur simultaneously, the path of the "suspension charging state duration > sixth time threshold t4 or the duration in the sleep state > seventh time threshold t5" is preferentially executed.

According to the charging state control method provided by the embodiment of the application, the power consumption of the power supply equipment can be effectively saved and the service life of the power supply equipment can be prolonged by judging the time-out to control the closing of the access module under the condition that the power supply equipment is in a pause charging state for a long time or the charging interface is in a dormant state for a long time.

In some embodiments, with continued reference to fig. 2, with state set 2, if a powered device unplug is detected, an enter device unplug state is confirmed and a wait for powered device to access or wait for powered device to begin a charge state is returned.

The path of the pluggable state detection has the highest priority. That is, when it is determined that the power receiving apparatus enters the apparatus pulled-out state, the determination is directly ended, and a new execution flow is entered.

In some embodiments, with continued reference to fig. 2, after the control path module enters the off state, it may return to waiting for the powered device to access or waiting for the powered device to begin a charging state, entering a new execution flow.

An implementation manner of plug detection of the power receiving apparatus is described below.

In some embodiments, the connection state of the powered device to the charging interface may be detected by detecting the connection state of the CC line of the Type-C interface.

In some embodiments, a weak pull-up and weak pull-down circuit may be provided on the Type-a interface DPDM line, and detect whether an external drive exists to determine the connection state of the powered device and the charging interface.

In some embodiments, whether the powered device starts charging may also be determined by charging current/charging power/whether there is a fast charge, etc.

Of course, in other embodiments, the plug detection and the detection of whether the charging of the device is started may be implemented in other manners, which is not limited in this application.

It should be noted that, the method for determining whether to meet the jump start detection condition based on the continuous number of times that the real-time electrical signal is greater than the sixth electrical threshold according to the embodiments of the present application may be implemented by various different means, such as performing the step through software program control, or may also be implemented by a hardware circuit, and various changes may be made to these embodiments without departing from the principles and spirit of the present application.

The implementation of this embodiment will be described below by taking a hardware circuit implementation of jump start detection as an example.

Fig. 6 illustrates a circuit configuration for realizing the jump start detection condition judgment.

The circuit is built by taking current as a criterion, and can realize partial algorithm functions.

Fig. 7 illustrates a sampling clock circuit Timer in which the sampling clock circuit generates a clock with a period of 50% duty cycle for sampling timing.

Fig. 8 illustrates a main sampling circuit, in which CSP and CSN are voltages at two ends of a current sampling resistor, and the sampled information can be equivalently converted into an output current.

During the first half cycle of the clock, S1 is closed, C1 charges, and the integration of the current will reflect the voltage magnitude at the hi_det point. S4 is closed, C2 discharges, and lo_det is clamped at 0.

In the latter half cycle of the clock, S3 is closed and hi_det is clamped at 0. S6 is closed, C2 is charged, and the integration of the current will be reflected in the voltage at the lo_det point.

Fig. 9 illustrates a hi_det judgment circuit, where when the voltage of the hi_det point is greater than a certain threshold value, the high current and time required for meeting the power jump precondition are considered, that is, conditions that the continuous number of times of meeting the real-time electric signal greater than the sixth electric threshold value is greater than the threshold value are met, and the jump detection function is turned on, and the hi_exists will be set high.

Fig. 10 illustrates a transition determination enable signal circuit by which the transition detection function is enabled after hi_exists is set high, and the transition detection signal is set high for a time period t 8. the transition detection function will be turned off after t 8. The real-time charging power is continuously smaller than the seventh electrical threshold P7 and the maintaining time period exceeds the eighth time threshold t8, and the circuit sets the sixth electrical threshold p3=the seventh electrical threshold P7 at this time.

Fig. 11 illustrates a lo_det decision circuit, which considers the low power required to satisfy a transition when lo_det is less than a certain threshold. When the rising edge of the Timer occurs, the One Shot circuit will generate a high level of 500ns, S7 is closed, and the judgment threshold of U2 will be switched to the threshold of low power required by the corresponding jump. When lo_det is smaller than the threshold value, the low power required by jump is considered to be satisfied, namely, the criterion that the real-time electric signal is continuously smaller than the first electric threshold value P1 and the maintaining time length exceeds the first time threshold value t1 is equivalent, the jump is considered to occur, and the powered equipment is in a suspended charging state.
